Abstract
The invention provides an image forming apparatus including an intermediate transfer belt composed of a resinous material, a transfer member for transferring a toner image on the intermediate transferring belt onto a transfer material, and an opposing member provided to be opposed to the transfer member across the intermediate transferring belt. The transfer member and the opposing member can be mutually pressured, and the intermediate transferring belt and the opposing member have an integrally measured microhardness smaller than 97°. Thus the invention provides an image forming apparatus capable of preventing a transfer unevenness caused at the transfer of the toner image from the intermediate transferring belt to the transfer material, and an intermediate transfer unit which is detachably attachable to the image forming apparatus.
